IMPROVEMENT IN CARPET-FABRICS.

Specification forming part of Letters Patent No. 162,385, dated April20, 1875; application filed March 13, 1875.

To all whom it may concer-n Be it known that I, SAMUEL HORNEE, Jr., of

Philadelphia, Pennsylvania, have invented an Improved Carpet-Fabric, ofwhich the following is a specification:

The object of rny invention is to manufacture a dainask carpet-faln-ic,in which the etfect of an additional ply is produced without theemployment of an additional set of figuring warp-threads, and thisobject I attain in the manner in which I will now proceed to describe,reference being had to the accompanying drawing, in which- Figure l is aface view of a strip of my im proved carpetfabric; and Figs. 2, 3, and4, diagrams, illustrating the construction of the saule.

The drawing illustrates my invention as applied to a two-ply fabric, Aand B representing the two sets of warp-threads, D the thick weft orlilling threads, a the fine wefts, and b fine warp-threads introducedfor a purpose explained hereafter.

In ordinary damask carpet-fabrics, the thick weft or filling threads areentirely concealed from sight, being embedded between the warpthreadswhich form the front and back of the fabric, so that the production of atwo, three, or four ply pattern requires the employment of a like numberof sets of warp-threads. I attain the e'ect of an additional ply withoutthe use of an extra set ofgurin g warp-threads by sinking all the saidwarps to the back of the fabric, at the proper points, by means of thejacquard, thus bringing the thick weftthreads to the face to aid informing the pattern.

The warp-threads A and B are controlled both by a jacquard apparatus forlifting the proper threads to form the pattern, prior to theintroduction of the thick weft-thread D,

and by a set of ordinary harness by which the threads are lifted inalternate sets, after each insertion ot' the thick wefts, for the in-Sert-ion ofthe fine weft-threads u..

To prevent the iioating of the thick weftthreads D, where they arebrought to the su rface, and to bind the whole fabric firmly together, Iemploy in the present inst-ance two sets of line warp-threads, b, whichare lifted' alternately prior to the insertion of the said weft-threadsD.

The fine warps b are not lifted with the warps A and B, prior to ltheintroduction of the line wefts; hence each thread I), afl er passingover one of the thick wel'ts D, passes under two tine wefts and a thickweft before again passing over a thick weft, as shown in Fig. 2, theeffect of this operation being to firmly bind the said threads D to thebackingthreads, and to form a compact fabric.

It will be evident that, although I have illustrated and described myinvention as applied to a two ply fabric, it may be applied with goodresults to fabrics having three or more sets of warp-threads, and thatit may also be applied to shawls or other fabrics.

I claim as my invention- A damask carpet-fabric in which the entirenumber ot' figuring warp-threads are carried to the back of the fabric,at intervals in order to allow the thick weft or lling threads to bebrought to the surface, all substantially as and for the purpose setforth. n

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
